Appendix A <br />Geotechnical Field Exploration and Testing <br />Report No. 20-14448 <br /> <br /> <br />Appendix A - Page 2 of 2 AMERICAN ENGINEERING TESTING, INC. <br />The boring logs include descriptions of apparent geology. The geologic depositional origin of each soil layer is interpreted <br />primarily by observation of the soil samples, which can be limited. Observations of the surrounding topography, vegetation, and <br />development can sometimes aid this judgment. <br /> <br />A.4 WATER LEVEL MEASUREMENTS <br /> <br />The ground water level measurements are shown at the bottom of the boring logs. The following information appears under <br />“Water Level Measurements” on the logs: <br /> Date and Time of measurement <br /> Sampled Depth: lowest depth of soil sampling at the time of measurement <br /> Casing Depth: depth to bottom of casing or hollow-stem auger at time of measurement <br /> Cave-in Depth: depth at which measuring tape stops in the borehole <br /> Water Level: depth in the borehole where free water is encountered <br /> Drilling Fluid Level: same as Water Level, except that the liquid in the borehole is drilling fluid <br /> <br />The true location of the water table at the boring locations may be different than the water levels measured in the boreholes. This is <br />possible because there are several factors that can affect the water level measurements in the borehole. Some of these factors <br />include: permeability of each soil layer in profile, presence of perched water, amount of time between water level readings, <br />presence of drilling fluid, weather conditions, and use of borehole casing. <br /> <br />A.5 LABORATORY TEST METHODS <br /> <br />A.5.1 Water Content Tests <br />Conducted per AET Procedure 01-LAB-010, which is performed in general accordance with ASTM: D2216 and AASHTO: T265. <br /> <br />A.6 TEST STANDARD LIMITATIONS <br /> <br />Field and laboratory testing is done in general conformance with the described procedures. Compliance with any other standards <br />referenced within the specified standard is neither inferred nor implied. <br /> <br />A.7 SAMPLE STORAGE <br /> <br />Unless notified to do otherwise, we routinely retain representative samples of the soils recovered from the borings for a period of <br />30 days.
